Full Stack Web Developer Roadmap

Free courses in the order a full stack web developer needs them: HTML, CSS and JavaScript for the page, TypeScript and React for the interface, Next.js for the server, SQL for the data, then Linux, Git and Docker to ship it. JavaScript runs on both sides, so you learn one language and use it end to end. Every lesson runs in your browser and every course section ends with a free certificate.

Step 1
HTML and CSS: the pageDedicated page
Start this stepStartElements, links, forms and semantic markup, then selectors, the box model, flexbox, grid, responsive layouts and transitions across two CSS sections. The forms you write here are the same ones your server reads later in the path.Start Dedicated page

Step 2
JavaScript and TypeScriptDedicated page
Start this stepStartFundamentals, logic and control flow, objects and classes in three sections, then TypeScript: types, interfaces, generics and reading the compiler's errors. This is the language you write in the browser and on the server, so it gets more time than any other step.Start Dedicated page

Intro to Variables

Audio

A variable is a named container that stores a value you can reference later in your program.

In Python, you create one by writing the name, an equals sign, then the value you want to store.

The value can change over time - reassigning the name simply points it to a new value.

Why learn full stack development on Coddy

One language on both sides. The path teaches JavaScript and TypeScript for the browser, then uses the same language on the server through Next.js route handlers and server actions, so the back end is new ideas rather than a second language to learn from zero.
Nothing to install. HTML and CSS render live beside your code, SQL runs against real tables, and the Linux, Git and Docker steps give you a real terminal in the browser. You can study the whole stack on a laptop that has never had a developer tool on it.
AI hints that read your code. When a component does not render, a query returns the wrong rows or a command fails, Bugsy looks at what you wrote and points you toward the fix without handing over the answer.
The order is the point. Most full stack courses rush to a framework in week two; this path gives JavaScript three sections and the browser a fourth before React appears, because a framework is only readable once the language under it is.

Frequently asked questions about becoming a full stack developer

What is a full stack developer?

A developer who can build both halves of a web application: the front end that runs in the browser (HTML, CSS, JavaScript and a framework such as React) and the back end that runs on a server (request handling, business logic and a database). In practice most full stack developers are stronger on one side, but they can ship a feature from the database table to the button that uses it without handing it to someone else.

How do I become a web developer?

Learn HTML, CSS and JavaScript well enough to build a page from a blank file, add one framework (React), learn how a server answers requests and how data is stored (Next.js and SQL on this path), learn Git, and build projects you can put online and explain. Employers hire on what you can show them, so the projects matter more than any certificate. This path is that sequence, in that order, and it is free.

Should I learn front end or back end first?

Front end first. You see the result of every line on the screen, which makes mistakes obvious and keeps motivation up, and the back end is much easier to understand once you have built the page that calls it. That is why this path spends its first four steps in the browser and only then moves to the server and the database.

Why does this path use JavaScript on the server instead of Python?

Because JavaScript is the only language that runs in the browser, so using it on the server as well means one language for the whole stack. Next.js, built on React, lets the same codebase render pages on the server, answer API requests and handle form submissions. If you would rather write the back end in Python, the Backend Developer path on Coddy teaches the Python route.

Do I need a bootcamp to become a full stack developer?

No. A bootcamp gives you a schedule, a cohort and career coaching, and charges for them; the skills themselves are the same ones this path teaches, and free material covers them well. What a bootcamp cannot shortcut is the practice: hundreds of small exercises and a few real projects. If you can keep a steady hour a day without a teacher checking in, a free path gets you to the same place.

How long does it take to become a full stack developer?

Around nine to twelve months at an hour a day to reach a junior level. On this path HTML and CSS take six to eight weeks together, JavaScript and the browser two to three months, TypeScript and React about six weeks, Next.js a month, SQL three to four weeks, and Linux, Git and Docker another month. Building your own project alongside the later steps is what turns that time into a portfolio.

Does this path cover Node.js, Express, authentication or deployment?

Not as their own courses yet, and we would rather say so than pad the page. Server code on this path is written with Next.js route handlers and server actions, which run on Node.js, but there is no Express course, no course on connecting an app to a production database with an ORM, and none on authentication or deploying to a hosting platform. Those are on the curriculum roadmap and join this path as new steps when they ship.

Is this full stack course free, and do I get a certificate?

Yes. Every course on the path is free, including the lessons, the browser editors and terminal, the AI hints and the certificates. Each course section ends with a free certificate, verifiable at its own URL, that you can add to LinkedIn or a CV.
